In his Histories, Herodotus relates how the Persians would either make a decision while drunk and then review it while sober or make a decision while sober and then review it while drunk.
A student of the great texts, I find real value in this technique. Not only that, but I believe I have improved upon it. My solution? To remain always half-drunk and half-sober. That way, I can deliberate upon and also review important matters simultaneously. This is how I have become an expert decision-maker.
